MACHINE FOR SETTING EYELETS OR THE. LIKE.

To all whom it may concern .Be it known that I, ROBERT B. SMITH,

a citizen of the United States, residing at Quincy, in the county ofNorfolk and State or the like,'of which the following description, inconnection with the accompanying drawings,'is a specification, likereference characters on the drawings indicating like partsin the severalfigures. V

This invention relates to machines for setting eyelets or otherfastening devices insheet material and particularly to that class ofmachine having punching devices arranged to'perforate' the work andcooperating. setting devices arranged to insert viously punched hole.

An object of this invention is to provide a machine having an improvedorganization and arrangement of instrumentalities.

To this end an important feature of the invention consists in thecombination with a punch of a sectional punching die movable relativelyto the punch with its sections locked together to efiect the punchingoperation, and setting dies relatively movable to insert and clenchafasteneigin the work so punched. The provision. of locking means for thesectional die insures the maintenance of the complete contour of the diewhen the punching operation takes place and consequently and. clench aneyelet or the like in the piein a punching and fastener setting machineforate the work and for holding the die having a sectional punching dieof which the sections are arranged for independent adjustment. theaccurate positioning of the parts in assembling the machine and permitscompensation for wear or convenient adjustment for other purposes whilethe machine is in use.

against further longitudinal movement. As herein shown, this mechanismincludes a crank and link connection disposedto reach a dead point atthe conclusion of the punch- .ing'operation and so hold the die againstfurthermovement upon the punch.

The lnvention also contemplates the employment, 111 a punching andfastener setting machine, of a carrying member for the punching diewhich member is provided with ways for a movable separating device forthe die sections. This arrangement is advantageous from a'structuralstandpoint slnce the ways may be formed in the carrymg member moreeasily than they could be formed in the interior of the machine frame.

Stillanother feature'of the invention consists in a punching andfastener setting machine having a work table or plate located in aposition wherein itssurface is substantially flush with the sections ofthe punching die when the latter is in its initial position. Suchconstruction affords a continuous supporting surface upon which the workmay be moved in all direction and located with accuracv for thereception of the fastener.

Other features of the invention, including importantcombinations ofparts and details of design and construction, will be hereinafter morespecifically described and Reference is to be had to the accompanyingdrawings in which Figure 1 is a side elevation; Fig. 2 is a view inperspective of the working parts of the machine as located prior to thepunching operation, the work table being re moved; Fig. 3 is a similarview of the working parts as located after the punching operation; Fig.4 is a view in perspective showing the operating connections of thelower setting ie and the punching die; Fig. 5 is a plan view of the worktable.

Beforeproceeding to a detailed descrip tion of the machine it will beconvenient to state briefly its mode of operation and the generalarrangement of its working parts.

The machine comprises a frame 9. carrying a stationary punch 4; andupsetting die 6. Mounted in the frame 2 for movement most convenient foran operator.

upper branch or aw of the frame is ad usttoward and'away from said puncht is a sectional punching die comprising'the plates 10 normally locatedin the plane of the work table 62 upon which the work to be eyeleted isplaced. 'When the treadle rod is actuatedthe die plates are raisedthrough suitable toggle mechanism and the work is forced against thepunch and perforated. During this operation the lower setting die, whichis located beneath the punching die,

has-extracted an eyelet from the raceway 38 and immediately after thepunching operation the sections of the die plate are separated by awedge bar 27 and the. lower setting die emerges carrying the eyeletwhich is threaded on the punch 4, forced through the work and finallyclenched against the upsetting die 6. The lower setting die is thenretracted and the sections of the die plate are moved together anddownwardly thus allowing the eyeleted work to be removed from the punch.v

The frame 2 of the machine is of suitable shape to, support the workingparts at a slight forward inclination to the vertical which arrangementhas been found to be the In the ably mounted a normally stationary punching and upsettmg device comprismg the centrally disposed punch 4E andannular upsetting die 6. These devices may be adjusted in any preferredmanner, for example, by

means of an adjusting nut '7, and a set screw 8 is provided for lockingthem in any adjustable position. The end of the punch 4 is made squareexcept for a small central 'projection .9 which serves to force thepunching through the die plate.

The die which cooperates with the punch 4 is formed by two plates 10 ineach of which is formed a recess which constitutes one half of the die.The contacting edges of the plate are cut away except adjacent thedie-forming recesses in order to insure a more perfect fitting togetherof the plates;

I Each of the plates 10 is adjustably mounted 12 each consist in atransversely extending V in a holder 12, being slotted for the receptionfof the screws 11," and by loosening these screws opportunity isafforded for shifting the plates 10 to bring the recesses into regis,ftration or to bring the die so formed into alinement with the punch 1.The holders portion and a downwardly extending shank which is pivoted bya pin 13 to the plate 14 forming part of a square plunger 16. The uppersurfaces of the holders 12 are re cessed so as to receive the die plate10 with their, upper surfaces substantially flush with r the surfaces ofthe holders, in this way form ing a substantially continuous work supporting surface when the die is in operative position. The inner facesofthe shanks of each holder are beveled ofi-below the pivots 13 in orderto allow the lower ends to approach each other as the upper portions ofthe holders are swung away from eachother and acompression spring 18 islocated between lowerends of the holders which serves normally tomaintain the holders with the die plates in operative relation. "A. stoppin or stud 20, extending through the plate 14 and into the inner wallof the plunger 16 is arranged to fit into recesses formed in theadjacent faces of the holders l2. and deter mlne independently vtheoperative position of each holder, the holders being maintained inengagement spring 18. r I V A locking clamp 22 is provided forpositivelylocking together the holders .until with. the -.pin 20 bythe after thepunching operation. The clamp comprises two side pieces, arranged toengage frictionally with Q the sides .of the holders 12, and aconnecting plate to which is rigidly secured a downwardly projectingT-shaped member 28 the head of which is received in a correspondinglyshaped slot 24: in the'frame'of the machine. The arrangement issuch thatas the plunger 16 isfl elevated carrying theholders 12 toward the;

punch 4, the clamp 22 is carried up with the holders until the head ofthe T shaped member 23 engages the top of the slot 24 which occurs afterthe punchingjdie' has.

beenforced on the punch ffor a snliicient distance to punch a clean holein jthework. The upwardinovement of the plungergcon tinues, however andthe holders then fslide.

A, cylindrical plunger 30 is mounted for reciprocation in the lower jawof the frame in alinement with the stationary punchand ups'ettingdie 6,and carries the adjustably mounted lower setting die which is pro videdwith a yieldin glymounted center spindle 34c-for the purpose ofextracting an eyelet from thedelivery end of the raceway and carrying itto the upsetting die. At its lower end the plunger 30 isforked andconnected with a link 36 forming apart of the actuating toggle to bedescribed hereinafter.

The raceway 38 is supported on levers 40 and 42 which are pivoted to theframe. at 43 and 4%. The lever 42 has two spaced rollers arranged to beengaged by the upper and lower engagingfaces of an arm 47 which projectsfrom the rear side of the toggle link 36. In normal position thedelivery end of the raceway 38 standsin the path of the center spindle34, such position being regulated by the adjustable stop 48 whichencounters an abutment on a rearwardly projecting arm of the. lever 42..

When the arm 47 is moved upwardly its upper engaging face acts upon theupper of the. two rolls carried'by the lever 42 and moves the racewayrearwardly, after the plunger 30 has been elevated. slightly to causethe spindle 34. to impale the lower-- most eyelet in the raceway.Thelowermost eyelet is thus drawn out of the raceway and the lattermoved to an inoperative position. On downward movement ofthe arm 47 thelower engaging face acts on'the lower roller of the lever42 and movesthe raceway forwardly to its normal position. The mechanism abovedescribed for operating the raceway is substantially similar to thatdisclosed and claimed in United States Patent No.

The working parts of the machine are actuated by a treadle rod 50through a lever 52 and a system of toggle links- Of these, the link 37is pivoted to the inner end of the lever 52 and link 36 is pivoted tothe lower end of the plunger 30, as shown in Fig. at. A radius link 54.fast to the rock shaft 55 is pivotally connected to the knuckle of thetoggle and serves to guide itsmoti on in an are about the rock shaft ascenter. The rock shaft55 projects through one side of the frame and onits outerend is provided 'with'a crank arm'56 which is connected withthe squared plunger 16 through the medium of a link 58 and stud 59.Another link 60 is also pivoted to the knuckle of the toggle 36, 37 andthis link is connected with and actuates the separating bar 26.

The toggle and the various connecting links are so proportioned andarranged that, on downward movement of the treadle rod 50 the plunger16, the bar 26 and the plunget 30 are'all' elevated at about the samerateat first. The arm 56 and link 58, which it will beobserved,-constitute an independ' ent toggle in themselves, are soonbrought into alinement and the upward movement 7 of theholdersl2i-andpunching die therethe rear end of the raceway fore ceases. The upwardmovement of the bar 26 and plunger 30, however, continues ment and thislatter movement, as already explained, results first in the separationof the halves of the punching die and then in the setting movement ofthe lower setting die.

The treadle-rod 50 is moved upwardly to retract the plungers by aspring, not shown, and is limited in this movement by an adjustable stop51 on the lever 52 which engages with a fixed abutment on the frame ofthe machine. On the upward movement of the treadle rod 50 the lowersetting die 32 and the rod 26 are quickly retracted and the holders 12are allowed to close under the actuation of the spring 18. During thismovement the toggle 56, 58 is on or near its dead point and accordinglylittle or no movement is transmitted to the plunger 16 until the lowersetting die and the separator bar16have been retracted.

A hopper for eyelets is mounted upon 38 and is provided withan agitatorof any usual type preferably a brush having a downwardly 6X tendingspindle upon which is fastened a forked arm 71 which engages astationary stud 72 on the frame of the machine. It will be seen that asthe raceway and hopper 7 O are moved back and forth the arm 71 andconsequently the agitating brush will be oscillated and the eyelets willbe brushed out through the delivery ports to the raceway.

A work plate 62'is mounted on the front of the frame 2 by means of anangle bracket 64 and is arranged to surround the punching die plates andform a continuous surface therewith when the latter are in theirlowermost position, as shown in Figs. 1 and 5. At the rear of thepunching die the work plate is slotted and a gage 66 is adjustablymounted in said slot by the aid of which the position of the Work withrespect to the punch made be accurately determined. Other gages may beprovided if it is desired to locate the work with a greater degree ofaccuracy.

Inthe foregoing description the rod 56 has been described, for the sakeof clearness. as a treadle rod, but it will'be obvious that it isimmaterial. by what means this rod is actuated and it is within thescope of the invention to drive the machine from any desired source ofpower. It will also be apparent that, with slight modifications incletail, the machine may be adapted for setting other fasteners thaneyelets, such as lacing hooks, rivets, studs, or similar articles. Theemployment of the machine for setting such articles is contemplated bythe present invention and is within the scopethereof.
